How To Fit A Kitchen Sink

  1. Attach the clips
  2. Fit your taps
  3. Fit the strainer
  4. Add sealant to the underside
  5. Lower your sink into the worktop cutout
  6. Tighten up the metal clips
  7. Connect the water supply
  8. Add sealant

You will need:

  • Plumber’s putty
  • Silicone sealant
  • Screwdriver
  • Pliers
  • Adjustable wrench

First, size up your new kitchen sink against your counter top cut out. If you have done your measurements properly then the replacement should fit just fine. If it does not, then head up to our cutting your countertop step.

Step 1: Attach The Clips

First, attach the clips to the underside of the kitchen sink and fold them in toward the sink bowl.

Step 2: Fit Your Taps

Next, take the taps from the previous sink or gather our new taps and slot them into the corresponding holes atop the sink, ensuring you follow the manufacturer’s guide on all present spacers and O-rings.

If you have a mixer tap then you will only need one tap hole in your new kitchen sink. If you have a hot and cold tap then you will require two sink holes.

Step 3: Fit The Strainer

Take your drain strainer and apply a small consistent ring of plumber’s putty around the underside of its lip. Screw it in tightly, ensuring a smooth fit with the putty.

Lean the kitchen sink on its side and apply the rubber gaskets and threaded flange to the underside of the drain strainers. Cross-reference your work with the manufacturer’s instructions to ensure proper installation order of these components. Then wipe away any excess with an old towel.

If you are reconnecting a food disposal unit and other specialist units, follow the manufacturer’s instructions and reconnect the brackets to the bottom of your new sink in the correct manner.

Step 4: Add Sealant To Your Sink

With all of your sink equipment connected to your new kitchen sink, run a bead of silicone sealant around the underside of the edge of the sink.

Step 5: Lower Your Sink Into The Worktop Cutout

Carefully lower the sink into your counter top cut out ensuring that you set the unit squarely.

Step 6: Tighten Up The Metal Clips

Time to dive back under and flip those metal clips outward then get out the trusty screwdriver and tighten them up against the underside of the counter top, locking your new kitchen sink into place.

Step 7: Connect The Water Supply

With the kitchen sink secured, take your adjustable wrenches and connect your tap lines back to your home’s water supply lines. Be extremely careful when attaching these that the threads are lined up so as not to strip the threads.

Reconnect your food disposal units and other specialist connections such as dishwasher drain in line with the manufacturer’s instructions. Then reconnect the drainline with your pliers.

Reconnect all power to your specialist connections such as food disposal units, then it is time to turn back on your water supply.

You can’t relax just yet – first, we must run the system and check for leaks.

Step 8: Add Sealant

If you are sure everything is connected correctly and there are no leaks, you can run a bead of sealant around the top edge of the sink to create a waterproof seal. Remember to allow this to cure properly before using your sink.
